8 BRITISH CICAD.E. 



toria and G. aiujlica. It does not occur in Salilberg's 

 List of Swedish Cicadariae. 



The specimens drawn in my plate are from the cabinet 

 of J. W. Douglas, Esq. 



Length 3'00 millinit'tres, or 0-12 inch. 



FULGORIN^, Stal. 



Two ocelli on the cheeks, and sometimes a third at 

 the extremity of the frontal mid-carina. No stridu- 

 lating organs. Anterior thighs not thickened {iwn 

 rcnjiecs, Fieb.). Tegiike at bases of elytra small. 

 Elytra either hyaline or parchment-like. Neuration 

 often complex and indistinct. Limbus none. Poste-

 former author named the Fulgorid^ the third, and 

 Sahlberg the fifth, in their several systems. Mr. 

 Edwards, in his 'Synopsis' (the arrangement of 

 which I have very generally adopted in this Mono- 

 graph), does not formally include British forms under 

 the head Fulgorid^ ; but places Gixius and Delphax 

 under sub -families designated by their respective 

 names. 



Burmeister probably gave the name Fidgora to the 

 exotic lantern-flies, as suggestive of the luminous 

 property then popularly believed to reside in the 

 singular horny cases protruding from their thoraces, 

 which have fanciful resemblances to Chinese lanterns. 



Notwithstanding Madam Merin's well-known cir-

 of a Dutch newspaper by the light afforded by one of 

 these insects," no reliable Entomologist has confirmed 

 her statement of such a phosphorescence. A writer, 

 however, in the ' Ent. Month. Mag.' (vol. viii., p. 167) 

 calls attention to a statement made in Perry's ' Arcana ' 

 (an old book), doubtless on hearsay evidence, that
